My invention relates to improvements in putty retainers, this. application bein filed in response to a requirement for division made in my earlier applicationfSerial No. 344,640, filed March 6, 1929, for metal weather shields for doors and windows. In

7 the present application I have shown and ,m'frames of the type shown in my form'erfapdescribed my invention as applied to metal plication, butI alsocillustrate two modificati'ons adapted for use. in connection with.

frames formed of wood. This is,'therefore,,

. a companion application which includes subcation. H

ject matter divided from said former applt.

A general object of my invention is toprovide means for utilizing the adhesive quality I of the putty to make the weather-tight joint while covering and protecting the putty from disintegration, either by reason of exposure f to weather or to the attacks of birds or animals. i 1 i A further objectisto provide simple, in-

expensive and effective means, cooperative with the putty, for-making durable'we'ather- .tightjointsfor window glassand panels.

In the drawings Figure 1 1s a fragmentary elevation of a poultry house sash and door asseniblyto of one: of the intermediate or cross rails of which my invention has been applied; v

Figures 2, 3 and l' are sectional 'views,

taken on lines 22,33,- and A l, respectively, of Figure 1. I

Figure 5 is a fragmentary isometric view the sash, showing three anchor strips as they appear at -different stages of the glaziers operationianda fourth anchor strip injits final orshield retaining position,

Figures 6, 7 and 8 are; fragmentary views of woodensash, showlng modifications;

Like parts are identified'by the same reference character's throughout the several views.

' The sash frame 10 is provided with cross rails 11 and 12 which subdivide the frame and cooperate therewith in supporting the panesof glass 13; The rail 12 serves alsoto support a door ltconnected to that railby 'hinges15. H I

In the construction shown, the frame 10 is formed of metal having a web18 along the inner margin of the frame bar, said web having a shoulder flange 19 along its otherwise free 'margin which serves as a ledge-19 to support associated panes of' glass 13 The lntermedlate or cross rails 11 have slmilar ledges 20 (Figure 5). Each ofthese ledges j 19 and 20 has an obliquely upturned edge margin 21 which forms with the ledge and the web 18 or with the wall of the intermediate rail v11, a putty receiving space 22, this space being filled with puttybefore theassociated pane of glass 18 is applied to the ledges.

The cross rails 11; havedouble webs 18, each with a web 20, since they receive and support glass at both sides.

As shown in Figure 5, the intermediate rails are each preferably formed by folding a strip of sheet metal along its medial line and turning its marginal portions outwardly in; opposite directions to form'the ledges. 20 and then upwardly in an oblique planeto form the putty retaining members 21 for the putty receiving cavity 22.

Each of the webs :or pairs of slots25 and 26 at suitable interthe Weber of the frame member 11. and

turned. upwardly untilafter the glass has 18 is provided with sets been placed. in position, whereupon-the end of each strip which passes through the slot 25 may be bent downwardly along the sur face of the glass pending'application of another body of putty to'it's exterior surface,

iv weakening the structure.

Preferably each of these anchor strips is of staple form, with a middle portion 28 connecting elongated arms 29 and 30 of unequal length, the arm 29 being preferably longer than the arm 30, whereby it may be upturned across the edge of the glass, as indicated at 31 in Figure 5, and then bent downwardly upon the surface of the glass in the portion 32.

After the glass has been placed in position, and the arms 32 of the anchor strip folded over upon its outer surfaces, the glass retaining band or'body 35 of putty is then applied in the usual manner to secure the glass to the frame, this band or body of putty being preferably triangular in cross section in accordance with the usual practice.

Thereupon a strip of metal, in the form of a shield 37, having a width corresponding r substantially with that of the oblique surface of the putty band, will be applied thereto and secured by folding the extremities 38 and 39 of the anchor strips over the edge margins of the shield 37. This shield is preferably slightly ribbed or corrugated, as indicated at 40 in Figure 5, whereby the same is sufficiently reinforced to allow very thin material to be employed without danger of displacement.

My invention is particularly applicable to metal sash frames, formed of sheet metal or other material which can be readily slotted to receive the anchor strips without material- It is also applicable to wooden sash frames in a slightly modified form as shown in Figures 6 and 7. By this modified form of construction, staples are employed to secure the anchor strips in position, and in Figure 6 I have illustrated a sheet metal staple 42 which engages the middle portion 28a of a sheet metal anchor strip, the staple being so located that the longer arm, 2964, may be upturned across the edge of the glass as indicated at 31a, thereby making it possible to use the anchor strips in the same way, or to use anchor strips exactly like those shown in Figure 5.

In Figure 7 a wire staple 43 is used 1n connection with wire anchor strips, otherwise similar to those shown in Figure 6. The Figure 8 modification preferably employs fiat metal anchor strips 43 and 44, each having its inner end elbowed and tapered to provide a tack-like point which may be driven into the wood to connect the associated anchor piece thereto. In this construction the two arms of the anchor are separately connected with the wood.

In Figure 6 parts corresponding with those or to form an air-tight closure for any other type of joint having a support to which putty may adhere.

From the foregoing description it will be understood that my invention permits a glass pane or other platelike member to be secured in a frame opening by a body of putty in adhesive relation to the frame and the platelike member or pane of glass substantially in accordance with common practice as heretofore followed, but with the additional protection afforded by the shield, and the additional security in the fastening of the shield, due to the fact that it is connected with the frame along opposite margins. It is thus possible to utilize, to the fullest possible extent, the adhesive characteristic ofthe putty, whereby air and water are excluded from the joint.

Also, the anchoring strips are themselves anchored by the edge of the glass as well as by their inter-lock with the frame, and in the structure shown in Figures 1 to 5, inclusive, the body of putty extends entirely around the edge margins of the glass and is,- in part, covered by the ledge 19 (or 20)."

Ordinarily the body of putty on the ledge will remain soft until the pane of glass has been placed in position and the putty applied to the opposite side, in which event, the two bodies of putty will merge and form a homogeneous mass.

1 claim:

1. The combination with a support, of a member in jointed connection therewith, a body of putty covering the joint, and. a thin strip of metal covering the putty and separately anchored to the support at intervals along each side margin, said body of putty being in adhesive engagement with the support and said member between said points of anchorage. 2. The combination with a support having pairs of slots at intervals along its length and provided with a shoulder having a putty retaining channel, a plate-like member engaging said shoulder substantially in the plane of one slot of each pair, with putty interposed between it and said shoulder, a body of putty connecting the support and plate-like member on the side opposite that occupied by the shoulder, a shield covering said body of putty, and anchor strips extending through said slots and along two sides of the body of putty, and having extremities engaging opposing margins of the shield at intervals along its length.
